construct/mc bibd: a task in MathConstructOptimize-Envs-harbor (Harbor dataset). A balanced incomplete block design BIBD(31, 15, 7) is a collection of b = 31 blocks, each a set of 15 distinct points from {0, 1, ..., 30}, such that every pair of distinct points is contained in exactly 7 of the…
The task
A balanced incomplete block design BIBD(31, 15, 7) is a collection of b = 31 blocks, each a set of 15 distinct points from {0, 1, ..., 30}, such that every pair of distinct points is contained in exactly 7 of the blocks (consequently every point lies in exactly r = 15 blocks). The same block may appear more than once.
